[5.9.1-rt20] affine_move_task does not always release rq lock

[Joe Korty <joe.korty@xxxxxxxxxxxxxxxxx>]

FYI. There is one path through affine_move_task() which
does not release the rq lock.  This appears to be in error.

	 * Either way, we really should have a @pending here.

	if (WARN_ON_ONCE(!pending))
		return -EINVAL;
